+# **Dataset Description**
+
+This dataset was created to support Article X and is available on [Roboflow](https://universe.roboflow.com/visiongauge/utm_dataset-ooorv) and [Hugging Face](https://huggingface.co/datasets/claytonsds/UTM_Dataset).
+
+It consists of images of **U-tube manometers** constructed using a **transparent PVC water level hose (5/16" × 1 mm)** and **flexible measuring tapes of different colors**, each with a length of **150 cm (60 inches)**. The manometric fluids represented in the dataset include **water, oil, and dyed water**. The dataset is intended for testing ML models for reading liquid column levels.**.
+
+The dataset includes  **904 unique original images**. All annotations were performed using the RoboFlow Annotate Tool, with label precision within ± 0.1 cm.

+
+# **Dataset Split**
+![dataset distribution](https://github.com/ClaytonSdS/VisionGauge/blob/main/steps/dataset_distribution_hf.png?raw=true)
+
+* **Test set:** 904 images
+
+# Data Structure
+
+The dataset follows a standard split structure:
+```
+dataset/
+├── test/
+│    ├── 10.0/
+│    └── ...
+└── dataset_mapping.csv
+```
+
+* Each subfolder name corresponds to the **label value** (e.g., water column height in centimeters).
+* Images inside the folder share the same height value.
